Citing your sources is an essential part of writing any research paper. It shows that you have done your homework, gives credit to the original authors, and helps your instructor see how you have used those sources to support your ideas.
Use both in-text citations and a Reference List (or Works Cited page) to show where your information came from. This not only strengthens your work but also allows readers to find and learn more about the sources you used.
You should cite any material that is not your own original thought — including direct quotes, paraphrased ideas, facts, statistics, or opinions from someone else’s work. Proper citation shows academic integrity and avoids plagiarism.
You do not need to cite common knowledge — information that can be found in at least five credible sources and is widely accepted as fact. For example: "Presidents’ Day is celebrated on the third Monday in February."
If you are ever unsure whether something needs to be cited, it is better to cite it than risk academic dishonesty.
